Thanks for the patience on this issue
A brief update here. We have identified the problem and we are currently working hard on getting a resolution in place as soon as possible.
Special thanks to those who have completed a full bug report. These have been really useful in helping us identify the issues.
Just as a sidenote here, the 500:H error is to do with the Podium Pass. This error doesn't affect the core gameplay at all, and shouldn't affect your in-game experience due to the lack of active Podium Pass series at this time.
